  If your DUROMAX Portable Generator's engine won't start, several factors could be at play. First, ensure the engine switch is set to “run” and the fuel valve is open. Check that the choke is closed and that the generator has sufficient fresh fuel. If the fuel is old or contaminated, replace it. Inspect the spark plug; clean it if dirty or replace it if broken. Also, make sure the generator is on a level surface and that the oil level is adequate, adding or changing oil if necessary.

  If your DUROMAX Portable Generator runs but provides no electrical output, there are a few potential causes. Initially, verify that the circuit breaker is turned “on”. A bad wiring connection could also be the culprit, so consider replacing the extension cord(s). Finally, the device connected to the generator may be malfunctioning; try disconnecting it.

  If your DUROMAX Portable Generator runs but struggles to support all connected electrical devices, it might be overloaded. Try disconnecting one or more items to reduce the load. A malfunctioning device could also be the issue, so disconnect any device that might be faulty. Also, check the air cleaner; if it's dirty, clean or replace the air filter.
